Only from the point of view that this is the first coin I have used in a domestic transaction with a monarch other than The Queen.
Apart from that it's just as collectible as any other 50p to me. If I come across a commemorative I keep them but I have little interest in modern mint issues. The quality of our coins has taken a real nosedive in the last 20 years. I mean, Paddington? F****** Paddington?
